Good looking puppy! I also had to get creative with my current puppy, because she'd learned just about all the standard obedience commands by that age.
A few suggestions I can think of would be "place" - meaning go to your bed or pad and stay there until released; "leave it" - meaning whatever you're messing with or focused on, don't!; crawl - basically stay very low to the ground while moving forward; stay - self explanitory, but something you can improve on incrementally in terms of both distance and duration; shake or paw - meaning give me your front foot; backup - meaning walk backward; stand - meaning from a sitting or down position get on your feet; spin - also self explanatory, but fun; forward - meaning move forward slowly, not the same as come or here, it just means advance forward slowly; go out - meaning teach the dog to run out to a particular spot or object, lots of videos online that show not only what this is, but how to go about teaching it; come away - which for my dog means come back away from where you're at, but not necessarily to me; boom or bang - meaning lay flat or "play dead"; wait - which again, for my pup, means stay near me, or inside the car or house until released to proceed.
There's more I can think of, but there's a start. Of course training at that age is all about fun! Keep sessions lite and fun and short, using lots of treats and praise. Be animated and fun! It's truly amazing what these dogs are capable of! Enjoy your puppy!
